Homework Help: chemistry

how to solve for a 28.4 L sample of methane gas is heated from 35.0 C to 76.0 C. The initial pressure of the gas is 1.00 atm at 35.0 C. Assuming constant volume, what is the final pressure of the gas?

OK, I did the following:

P₁ = 28.4 L P₂ = ?
T₁ = 41.0◦C T₂ = 35.0◦C
+273.15K= +273.15 K=
314.2K 308.2K

P₁T₁ = P₂
T₂

(28.4 L)(314.2 K) = 29.0 L
(308.2 K)

Do my answer looks correct which is 29.0 L
